Little Nightmares

Little Nightmares is an eerie puzzle-platformer from Tarsier Studios. You play Six, a small girl in a yellow raincoat who is lost inside a gigantic vessel called the Maw. Distorted, bloated adults live all around, and any encounter with them can be your last.

The game asks for caution rather than strength: you crawl, hide in shadows, climb furniture that looks enormous and solve light spatial puzzles. Scale feeds the atmosphere, and something as simple as a door handle becomes an obstacle. There is almost no spoken dialogue, and everything is told through the image.

According to HowLongToBeat (via DekuDeals), the story takes about 3.5 hours, with extras about 5, and a full run about 9. At about 2 hours a day (roughly 60 hours), a month is plenty with room to spare. The game is single-player, so it is fully available under the offline rental.
